Chemical defence strategies of higher fungi.

Like plants, fungi have evolved a variety of defence strategies in order to protect themselves against feeding mammals, insects and infection with parasitic fungi. In contrast to plants little is known on the chemical ecology of fruiting bodies of higher fungi, particularly those defence mechanisms which are induced upon wounding have only occasionally been recognised. Methods both for the detection of permanently present defence compounds and for the elucidation of wound-activated chemical defence mechanisms are discussed in this concept paper.
